This is incorrect. A reference to an open file stays perfectly valid
regardless of what is done to the name of the file. You can even remove
the file entirely and any previously opened file handle will continue to
function (and take up disk space!).
Renaming a file changes the way you get access to the underlying
file object but does not change the object itself. Since a file handle
that a process has refers to the the underlying object, not the name,
output will continue to be written to the original file and the new
catalina.out will remain empty.
